> Currently in order to define an ACID table, the following three conditions need to be satisfied:
> * tblproperties ('transactional'='true')
> * table has to be bucketed
> * table format has to be stored as ORC
> If any of the above condition doesn't hold, the table won't be ACID compliant, and query result against the table will be unexpected.
> HIVE-12064 made sure that reverting tblproperties 'transactional' from 'true' to 'false' is not allowed. But changes for the other two conditions are still not restrained.
> We need to make sure an ACID table cannot be un-bucketed, and cannot use other data format other than ORC.
